<p>In order to manufacture sports footwear (1) with a soft, yielding upper (1) an inner boot (8), in which a chamber for the injection of an expandable resin is defined, is provided inside the upper (2), the footwear (1) is fitted on the foot, and a containment structure (10), independent of the upper (2) and of the inner boot (8), is applied to the footwear in order to limit the deformation of the footwear (1) owing to the expansion ressures of the resin, a resin is injected into the inner boot (8) in the fluid state and, after the resin has expanded and at least partially set, the containment structure (10) is removed from the footwear (1). <IMAGE></p> |
